All my tanks except the 125g are in my basement. We heat with wood & the weather here had been arctic like -30/40 on & off for a few weeks. All tanks have at least 1 300w heater some have 2 that generally keep the water between 78/81 but with this weather the temp has fluctuated as low as 75 at night because the woodstove can barely keep the house at 65 let alone throw off extra heat to assist heaters in keeping tanks warm. I know fish can tolerate a vatiance in water temperature but how much & for how long before it becomes an issue that requires more attention than making sure the heaters are working
